IMPROVEMENT lN PlPE-ORGANS.

Specification forming part of Letters Patent No. 172,307, dated January 18, 1876; application filed September 8, 1875.

To all whom it may concern:

Be it known that I, AUGUSTUS BERNARD FELGEMAKER, of Erie, in the county of Erie and State of Pennsylvania, have made certain Improvements in Portable Pipe-Organs,

of which the following is a specification:

This invention is an improvement on the patent granted to myself and Silas L. Derrick,

dated May 5, 1868, and numbered 7 7 ,7 03; and

the invention consists in the application of.

two wind-chests to a portable pipe-organ, (one set on top of the other,) and their arrangement in relation to two rows of keys or manuals.

in vertical cross-section; Fig.2, a plan; and v Fig. 3 a front view, with the case removed.

A represents the usual wind-chest of a portable pipebrgan, a. a, showing the pipes leading from the air-passages, and in connection with the usual key-board B. A is a second windchest set over or on the first one, and whose pipes at a, through their appropriate channels, are operated by a second row of keys or manual, B. The two manuals and two windchests are for the purpose of giving greater scope to this kind or class-of instruments, so as to allow of a greater variety of tone or stops, and this is accomplished by providing the second row of keys B and the separate wind-chest A for that set or manual, thus permitting a player to get what are known as solo efl'ects, one manual being used for those and the other for the accompaniment. Either manual may represent the solo-stops.

The manner of operating with the second wind-chest is as follows: The push-pins b b (see Fig. 1) leading directly from the keys B of second manual, operate the levers c c, which are pivoted in the middle at d. The pressure on the key forces down the push-pin, which thrusts down the back end of said lever and raises the front end, drawing up with it, by means of a connecting-wire, e, the wind-valve The invention further consists in the man f, and unclosing the opening to the channel leading to the pipe 0/. The first row of keys B actuates the valves of the regular wind- -chest A in the usual manner, the push-pins g g operating directly on the valves h h.

The construction of the push-pins g g or stickers, is peculiar, and is for a threefold purp0seviz., to level the keys, to couple the manuals, and open the valves h h. Between the upper portion g and lower part g of each push-pin is an interposed threaded wire, 1', and an adjustable nut, 70, set at a certain position on the wire, the object to be presently explained. The keys of the lower manual each rest on the upper part g of each push-pin, and, by turning this upper part g up or down on the threaded wire 1;, the key is kept level with the next one, and so on through the whole manual. The nut is on each pin is used in connection with the coupling devices, which are as follows: On top of the valve-chamber G (which. sets over wind-chest A) is arranged the lever coupling-bar D, and which is raised up and lowered in a frame, I, by means of a flat draw-slide, m, setting underneath, (and which is attached to a rod, a, leading to the stop 1),) and by inclines'r 1" (see Fig. 3) on the slide m, working in corresponding inclined slots in the coupling-bar in its under side. In this coupling-bar are pivoted the independent levers s s, with their outer ends forked, as shown fully in Fig. 2, and which inclose the threaded wire t of the push-pins g, and just below the adjustable nut 70. The back ends of these levers come just beneath the front ends of the levers c c of the second manual, but do not interfere with their working until the slide on is drawn by the stop 19, which throws the front ends of the levers s 8 up in connection with the nut 10, on the front push-pins g. Therefore, when the keys of the first manual B are pressed down the push-pin g is operated, opening the valve h. The nut it forces down the lever s, and this throws up the lever c, which opens the valve f simultaneously with the other h, thus coupling all the notes together and getting a double efi'ect. Even when the coupling-stop is pulled out, the second manual B will still operate independently.

All this action is very simple, and is situated immediately under the key-board, and is no longer than the length of the keys, leaving plenty of room behind for the pipe-work, &c.

E represents the usual bellows or feeder to the organ. This is blown either by footpressuremn the front lever t or by a hand-le-' ver, u, at the back. Their independent arrangementis one of the features of this in vention. The foot-lever t is pivoted ate, and has a length of webbing w attached to its inner end, (see Fig. 1,) and also to a bar, F, on the bottom of the feeder E. The hand-lever u is pivoted at y, and has also a piece of webbing, 2, attached to'its inner end and to the same bar]? of the feeder or bellows. Suitable springs are arranged in connection with the. levers t u to return them to position. By this simple arrangement either lever can be operated entirely independent of the other.

I claim 1. In a portable pipe-organ, the two windchests, A A, and their respective air-channels and connections, with the two manuals or banks of keys, B B, all combined substantially as and for the purpose specified.

2. The stickers or push-pins for the lower key-board B, constructed in two parts, 9 g, and having the interposed threaded wire i and put it, as and for the purpose specified.

nut is, slotted levers s s,

3. The combination of the push-pins g g i, and lever-bar l), for the purpose of throwing said levers in connection with levers 0 c to couple or uneouple the two manuals, as hereinbefore specified.

4. The key-leveling device, consisting of the upper part g, of the push-pin, and the interposed threaded wire 2', substantially as specifie 5. The foot and hand levers t u and webbing w z, in connection with the feeder E and bar F, for the purpose of getting independent action from either lever, combined and arranged substantially as specified.

6. In a pipe-organ provided with two manuals, B B, the two Windchests, A A, coupling devices D m, levers c s, push-pins g 9, wire 6, and nut k, all constructed and arranged substantially as and for the purpose described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
